ABSTRACT:
A trough-like deflector is attached to the body of a fiber chopper and extends outwardly from the lower portion of the chopper nozzle opening. The sides of the deflector are upwardly divergent to form a trough extending generally in the direction of the flow path of fibers normally ejected from the nozzle. The deflector skews the flow path of fibers ejected from the sides of the nozzle in an upward and inward direction. The deflector prevents the loss of chopped fibers to spurious air currents created by the ejected fiber stream and promotes a more uniform lay-down of fibers onto a substrate.
